Correct. The trick here is, the controler and model should be fairly static if you were presenting the same data via XML, HTTP+SOAP, HTTP+HTML, CLI etc. Then either your controller pushes the data to the view you somehow get a handle of, or the view pulls from the controller (through to the model) the data to present.

Same is true of the model. If your view and controller stay the same, your model should be fairly possible to replace without too much rigmarole
